12月的心境：一半優，一半喜，
12月的天空： 一半晴，一半雨，
12月的風 ： 已不再那么的輕柔 ，帶有無言的煩躁！甚至裹著疼痛的雨，
2022年的尾巴 ：已悄悄來臨！
臨近新的一年，小編為大家準備了一套系列《從簡易到豪華版——3個版的“飛機大戰”小游戲》
大家可以先自行💭想象~嘿嘿，等我慢慢更新這個系列，今天先給大家更新一個基礎版本的飛機大
戰吧！
其實說是基礎的話也不是很基礎：界面特別精致、然后還有相應的防護盾等功能，只是因為第一款
的飛機大戰是天上掉下隕石然后敵機的話沒得，等我給大家下次升級在給大家寫哈！
那么——我們就正式開始干活兒吧👇👇👇👇👇👇

故事背景：（純虛構，勿認真）
12月30號晚上凌晨，🌏發生隕石墜落，現場視頻顯示，當晚夜空忽然被照亮，一道紅光從空中劃
過，幾秒后迅速消失，經過研究，預計今天還會有新一波的大量隕石從天而降，甚至這大量隕石的
降落威脅到了人們的生活，造成了多起醫療事故，所以最后出動了保衛戰戰隊進行宇宙的隕石消滅
計劃！我們要盡可能的擊碎甚至消滅這些大量的隕石...........計劃開始........
一、游戲規則
我們設計了一款基于Python的Pygame模塊開發的飛機大戰游戲，
飛機大戰游戲是一款休閑益智類游戲，既簡單又耐玩，在初始界面，我們有開始游戲和退出游戲兩
個選項，
開始游戲后，玩家可以用上下左右方向鍵的控制飛機在螢屏上向任意方向移動，通過空格鍵射擊隕
石得分，有護盾加生命以及閃電?加攻擊炮彈，初始化生命為3次在螢屏右上角可以看到當前生
命，中間可以看得分，
二、準備中
1)素材圖片
2）來點兒Music
三、代碼演示
